"Ship 3D to the browser with Streamlit, FastAPI, Three.js and chunked streaming — one URL that opens on any client's laptop."

1. Course Overview

Dimension	Details
Format	Self-paced online course delivered through the 3D Geodata Academy LMS.
Price	€197 (excl. VAT). See section 7 for the legal payment terms.
Learning Objectives	Architect the backend: Design a FastAPI + PDAL backend that chunks LAS, E57 and PLY for browser consumption. (M1, M2) Integrate segmentation: Stream per-point labels alongside geometry with class toggles and export paths. (M3) Ship to the browser: Build a Three.js viewer and deploy to Streamlit Cloud, Fly.io or a VPS. (M4, M5)
Target Audience	3D engineers with mid-level Python who want to ship past the notebook — delivering point clouds and segmentation outputs to clients as a browser-first spatial web app.
Prerequisites	Working Python notions help. Watch the prerequisites primer →
Estimated Duration	Approximately 10 hours of focused work. Fully asynchronous.
Access	Direct enrolment via the 3D Geodata Academy. A 14-day legal cooling-off period applies.
Accessibility & Disability	All courses are open to learners with disabilities. A dedicated referent reviews each request to put the right pedagogical and technical adjustments in place. Referent: Dr. Florent Poux — howto@learngeodata.eu.

A note from Dr. Florent PouxThe most common message I get from students is some variant of 'my pipeline works but my client cannot open it'. The delivery layer is what opens up everything else. Once you master it, one good segmentation becomes a reusable product.

2. Technical Stack & Pedagogical Means

Software stack: Python and the standard 3D ecosystem (Open3D, Laspy, NumPy, PyTorch, CloudCompare, Meshroom — adapted to the course focus).
Hardware: any modern laptop (Windows, macOS, Linux). GPU recommended for deep learning modules.
Datasets: reference datasets and notebooks provided.
Infrastructure: proprietary LMS with 24/7 access, automated quizzes, progress tracking and digital course materials.
Modality: alternates theory and hands-on practice — code, real datasets, software use and shippable project deliverables.
Theory resources: video lessons, written handouts, curated research articles and PhD-level references.

3. Course Structure

Module	Title & Focus
M1	Backend Architecture FastAPI, job queue, storage and the directory structure that scales.
M2	Point Cloud Chunking Octree chunking and a streaming protocol that keeps 100M points responsive.
M3	Segmentation Integration Per-point labels streamed alongside geometry, model-agnostic.
M4	Frontend Viewer Three.js integration with orbit, select, measure and annotation.
M5	Deployment Ship to Streamlit Cloud, Fly.io or a VPS with auth and rate limits.

Why this structure, Dr. Florent PouxEach of the 5 modules ends with a quiz, and the quizzes are cumulative. Don't skip a module just because you think you know it. The gaps you didn't know you had show up in the final quiz.

M1 — Backend Architecture

FastAPI, job queue, storage and the directory structure that scales.

FastAPI service layout.
Async endpoints for 3D payloads.
Job queue basics.
Storage layer abstraction.
Project packaging.

M2 — Point Cloud Chunking

Octree chunking and a streaming protocol that keeps 100M points responsive.

PDAL chunking workflows.
Octree level-of-detail.
Binary payload formats.
Streaming protocol design.
Caching and CDN patterns.

M3 — Segmentation Integration

Per-point labels streamed alongside geometry, model-agnostic.

Model abstraction interface.
Per-point label streaming.
Class toggles and filters.
Confidence-based masking.
Export to LAS/CSV/IFC.

Mid-course checkpoint, Dr. Florent PouxWhen you reach M3 — Segmentation Integration, stop and apply what you've learned to a dataset you actually care about. The back half of the course goes faster when the first half sits on a real example, not a toy one.

M4 — Frontend Viewer

Three.js integration with orbit, select, measure and annotation.

Three.js scene setup.
Orbit, select, measure.
Annotation overlay.
Responsive layout.
Mobile-friendly controls.

M5 — Deployment

Ship to Streamlit Cloud, Fly.io or a VPS with auth and rate limits.

Streamlit Cloud deployment.
Fly.io and VPS options.
Auth and sharing links.
Rate limits and cost control.
Portfolio-ready spatial web app.

Expert tip — Dr. Florent PouxDo not try to be a JavaScript expert. The Three.js code in this course is deliberately small. Read every line, understand it, then stop. Ninety percent of your time should be on the backend and chunking.

4. Assessment, Certificate & Grading

This is a standalone course: there is no project to defend and no oral examination. Evaluation is fully quiz-based, automated through the LMS.

Stage	Activity	Validation
Before the course	Optional positioning quiz to calibrate prior knowledge.	Informative — no minimum score.
During the course	End-of-module quiz (one per module, 10 to 15 questions).	Score ≥ 70 % per quiz.
End of the course	Final quiz covering all modules.	Score ≥ 80 %.

Conditions to obtain the certificate

Validate every end-of-module quiz with a score of 70 % or more.
Validate the final quiz with a score of 80 % or more.
Quizzes can be retaken without limit; the latest score is retained.

Grading scale

Pass: all quizzes ≥ 70 % and final ≥ 80 %.
Pass with Merit: average across all quizzes ≥ 85 %.
Pass with Distinction: average across all quizzes ≥ 92 %.

Successful learners receive the course certificate (PDF + verifiable digital badge) and join the Alumni registry.

Accessibility & disability: all evaluations can be adapted (extended time, alternative formats, oral or written substitution, screen-reader friendly versions) on request to the disability referent howto@learngeodata.eu.
